Question

4. Find the value of k if x=2, y=1 is a solution of the equation 2x + 3y = k.​

Answer 1

X=2,Y=1

As per question,

2X+3Y=K

2×2+3×1=K

4+3=K

K=7(Ans)

Answer 2

$\sf\large{\red{★ᴀɴsᴡᴇʀ★}}$

Given equation is 2x+3y=k

According to question x=2,y=1

Now substituting the values of x and y in the equation 2x+3y=k,we get,

(2×2)+(3×1)=k

⇒ 4+3=k

⇒ 7=k

So, k = 7

So, the value of k, if x=2,y=1 is a solution of the equation 2x+3y=k is 7
